Boise and TCU will suffer too many losses at skill positions(Dalton most notably) to crack the BCS again.
Nebraska is a little overrated. We lose Amukamara, Hagg, Allen, Helu Jr., Paul, McNeill, Henery AND Kunalic(very important special teams players) among others I forgot.
We lose a lot of experienced talent on defense. And a few veterans on offense, and our fucking excellent kicker/punter. First year in the B1G(god that felt weird typing) Ten people are little over anxious, and over confident. I think we have a rough season defensively.
